We're going to turn to the royal portrait. Kate's first unveiled in london. This is the portrait that millions will see for years to come. Is it a success? You're going to be the judge right now.

Painter paul emsly says he wanted to capture her natural beauty. And he thought he was going to paint her without a smile. After meeting her, he changed his mind.
